ANTIFRIOTION-BEARING.

SPECIFICATION forming part of Letters Patent No. 687,954, dated December3, 1901.

Application filed December 19, 190i). Serial No. 40,343. (No model.) 7

To all whom it may concern.-

Be it known that I, SAMUEL S. EVELAND, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have inventeda certain new and useful Improvementin Antifriction-Bearings, of which the following is a specification.

The present invention relates to an improvement upon the bearings shownin Letters Patent No. 602,047, of April 5, 1898, to Hobron;

and its object is to enhance the efficiency of said device by increasingthe efiective length of the rollers without changing the size of thedevice as a whole.

To this and other ends the invention comprisestheimprovementshercinafterdescribed and claimed.

The nature, characteristic features, and scope of my invention will bemore fully understood from the following description,taken in connectionwith the accompanying drawings, forming part hereof, and in which-Figure 1 is an elevational view of an antifriction device embodyingfeatures of myin- Vention. Fig. 2 is a sectional View of a portion ofthe same.

In the drawings, 1 represents the rollers.

2 represents the roller-supports, having individual sockets 3 for therollers, and 4; repre sents the balls, interposed between the rollersand the supports. In the patented device above referred to the ballswere arranged in the sockets 3 and the rollers were necessarily somewhatshort in order to accommodate the balls. In the device constituting thesubjectmatter of this application auxiliary sockets are provided for thereception of the balls, so that the rollers may-be correspondinglyincreased in length, whereby their effective surface is also increasedand the device made more efficient as a whole. The oifsetted auxiliarysockets for the balls are independent of and smaller than theroller-sockets 3, and they are arranged in the ends of the rollers, asclearly shown in Fig. 2. The balls bear against the bottoms 5 of theauxiliary sockets, and it will be observed that they not only serve totake up end thrust, but also serve the important function of keeping therollers in alinement.

It will be obvious to those skilled in the art to which my inventionappertains that modifications may be made in details without .departingfrom the spirit thereof. Hence I do not limit myself to. the preciseconstruction and arrangement of parts hereinabove set forth, andillustrated in the accompanying drawings; but,

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-v Thecombination of the rollers having the squared sockets in the endsthereof and hottoms for the sockets, the roller-supports havingindividual sockets for the rollers, and balls arranged in-saidroller-sockets and sufficiently protruding therefrom to impinge againstthe supports, whereby to aline the rollers and take up end thrust,substantially as described.

In testimony whereof I have hereunto signed my name.

SAMUEL S. EVELAND.

In presence of W. J JACKSON, K. M. GILLIGAN.
